Verifying the configuration
# Use the following command to display information about the portal authentication server.
[Switch] display portal server newpt
Portal server: newpt
IP
VPN instance
Port
Server Detection
User synchronization
Status
The Up status of the portal authentication server indicates that the portal authentication server is
reachable. If the access device detects that the portal authentication server is unreachable, the
Status field in the command output displays Down. The access device generates a server
unreachable log "Portal server newpt turns down from up." and disables portal authentication on the
access interface, so the host can access the external network without authentication.
Configuring cross-subnet portal authentication for MPLS
L3VPNs
Network requirements
As shown in
A portal server in VPN 3 acts as the portal authentication server, portal Web server, and RADIUS
server.
Configure cross-subnet portal authentication on Switch A, so the host can access network resources
after passing identity authentication.

Configuration prerequisites
•
Before enabling portal authentication, configure MPLS L3VPN and specify VPN targets for VPN
1 and VPN 3 so that VPN 1 and VPN 3 can communicate with each other. This example
describes only the access authentication configuration on the user-side PE. For information
about MPLS L3VPN configurations, see MPLS Configuration Guide.
•
Configure the RADIUS server correctly to provide authentication and accounting functions.
Configuration procedure
Perform the following tasks on Switch A.
1.
Configure a RADIUS scheme:
# Create a RADIUS scheme named rs1 and enter its view.
<SwitchA> system-view
[SwitchA] radius scheme rs1
